These figures cover 264 flights between July 2025 and June 2026. Beyond the headline rate, 16.4% of arrivals land a full hour or more behind schedule. That is the number that wrecks a connection, and it is not visible in an on-time percentage alone.

Schedule

When B6 2185 flies

B6 2185 flies BOS to PIT without a single fixed slot. Its most common scheduled departure was 18:00, used on 27 of 264 flights. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.

A 18:00 departure sits in the 5pm–8pm window. Across every US flight scheduled in that window the on-time rate is 68.2%, and B6 2185 runs 5 points worse at 62.8%. By that time of day most aircraft have flown several legs already, and whatever went wrong earlier is still in the schedule.

Across the year

B6 2185 quarter by quarter

B6 2185 did not run the same all year. Its best quarter was Oct–Dec 2025 at 71.4% on time and its weakest Jan–Mar 2026 at 43.8%, a swing of 28 points on roughly 66 flights a quarter. The twelve-month rate averages over that, so if you are flying in a weak quarter the quarter's own figure is the better guide.

By weekday, B6 2185 did best on Saturday at 75.0% on time and worst on Friday at 43.9%. Each day rests on about 38 flights, so a gap of 31 points is worth noticing but could still narrow in another year.

Delay causes

Why B6 2185 runs late

One category carries most of the weight here. Late-arriving aircraft accounts for 63% of the 6,989 delay minutes carriers reported, and the remaining four split what is left. The split is by minutes rather than by flights, so a few very long delays count for as much as many short ones.

63%
Carrier

Extreme weather
4%

63% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. That is a cascade, and cascades start small and grow through the day. Across 6,989 reported delay minutes here, that single category outweighs weather by 17 to one. It is the strongest argument for booking the first departure of the morning, when the aircraft has been sitting at the gate overnight with nothing to inherit. The split is drawn from 6,989 delay minutes reported on B6 2185.

Cancellations run at 4.92%, against 1.81% nationally. That is about one flight in twenty cancelled outright. A cancelled flight is invisible in every on-time figure on this page, so the punctuality numbers above describe only the flights that actually operated.

Connections and routes

What a delay on this flight costs

For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 16.4% of arrivals land a full hour or more behind schedule, against 8.1% nationally. A 45-minute layover does not survive that, and no amount of walking quickly changes it. Ninety minutes is the honest minimum here, and two hours if the onward flight is on a separate ticket.

Every one of the 264 flights under B6 2185 in the data flew BOS to PIT. The number was not reused on any other city pair, which makes this a clean record of one route.

One caution: this is a thin sample. 264 flights over twelve months is enough to clear this site's floor but not enough to pin the rate down tightly, and a single bad week moves it by more than a point. Treat the grade as a rough reading.

What to do with this

Booking B6 2185

For a booking, the cancellation rate is the figure to plan around on B6 2185: 4.92% of its 264 scheduled flights did not operate. A late arrival costs a little over an hour, but a cancellation costs the day, so leave a later option open.
